FIELD AND BACKGROUND OF THE INVENTION

The present invention, in some embodiments thereof, relates to a body organ lumen cleaning system, and, more particularly, but not exclusively, to an integrated endoscope body organ lumen cleansing system (IECS).

While partially homogenizing food's original structure, gastrointestinal processing also adds new structure; for example, by aggregating digested particles, and by controlling stool water content. As captured by the Bristol Stool Scale, for example, stool is classified of a scale from 7 (completely liquid) to 1 (small hard lumps). Variables affecting the state of fecal aggregation and fluid content, as well as completeness of food digestion, include the frequency of defecation (normally ranging from five times a day to twice a week), and the speed at which food passes through the gastrointestinal tract (10 hours to 4 days is normal). Gut flora and secretions of the digestive tract also become part of the stool.

A colonoscope provides means for optically and/or electronically imaging the colon and its contents, for example, to look for cancerous and/or pre-cancerous polyps. For effective viewing, a common practice before colonoscopy is to clear as much of a colon's contents as possible, sometimes by aggressive changes to diet and/or by administration of purgatives. In some methods of colon observation, imaging occurs while flushing or washing a portion of the colon with an irrigating fluid. Irrigating fluid, fecal matter and/or other colon contents are drawn out of the colon by suction and/or other methods for transporting matter out of the body.

Reference is now made to FIG. 1, which is a plan view and simplified block diagram illustration of an integrated endoscope and cleaning system (IECS) in accordance with some embodiments of the invention. As shown in the exemplary embodiment depicted in FIG. 1, an IECS 100 comprises an endoscope 101 having an endoscope handle 102, an interface portion 116 and endoscope insertion tube 118 including a distal end tip 130 and a bendable portion 132. In some embodiments, endoscope 101 comprises a colonoscope. In some embodiments, IECS 100 comprises one or more lumen cleaning systems: an endoscope cleaning system (ECS) 150 and an independent cleaning system (ICS) 155.

In some embodiments, ECS 150 comprises an endoscope handle 102 in fluid and data communication with an Endoscope Working Station (EWS) 106 via at least one umbilical cable 104 carrying at least one or more air and/or water supply tubes in fluid communication with respective EWS 106 air 108 and/or water 110 sources communicating with respective air 178 and/or water 170 supply tubes and one or more suction tubes in fluid communication with an EWS source of vacuum 112.

Additionally and optionally, IWS 126 comprises at least one evacuation reservoir 121 and at least one processor 124 having a database and receiving data from and controlling one or more fluid pumps, light, image acquisition and power sources (not shown). In some embodiments, IWS 126 processor 124 is in data communication with handle 102 as indicated in FIG. 1 by an arrow designated reference numeral 145.

In some embodiments and optionally, ICS 155 comprises one or more fluid jet nozzles (not shown) configured eject fluid jets to agitate and break up matter in an examined lumen e.g., fecal matter in the colon. In some embodiments the jet nozzles eject directional fluid jets directed by IWS 126. In some embodiments, the jet nozzles are located adjacent a camera head and are directed to clean a camera lens from debris.

In some embodiments, endoscope handle 102 comprises at least one suction control valve 138 and at least one air/water control valve 140. In some embodiments, suction control valve 138 and air/water control valve 140 are configured to be activated manually by a user. Alternatively and optionally, in some embodiments, suction control valve 138 and air/water control valve 140 are in data communication with IWS 126 processor 114. Optionally, in some embodiments, suction control valve 138 and air/water control valve 140 are controlled by at least one of manually and IWS 126 processor 114. In some embodiments and as explained in greater detail elsewhere herein, endoscope handle 102 comprises at least one IECS mode of operation toggle switch 142. In some embodiments, mode of operation toggle switch 142 is configured to select between one or more modes of operation of IECS 100.

In some embodiments and as explained in greater detail in relation to embodiments elsewhere herein (for example, in relation to FIGS. 2A-2B, 3A, 4A, 5A, and/or 9) endoscope insertion tube 118 comprises at least one working channel 134 optionally functionally coupled to at least one EWS 106 vacuum source 112 as indicated by broken line arrow 147 and at least one fluid supply tube 148 comprising at least one of air 178 and/or water 170 supply tube in fluid communication with at least one of EWS 106 air 108 and/or water 110 sources. In some embodiments, endoscope insertion tube 118 comprises at least one evacuation tube 152 functionally coupled to at least one IWS 126 vacuum source 122 and/or at least one fluid supply tube 154 comprising at least one of air and or water supply tubes in fluid communication with at least one of IWS 126 air 128 and/or water 120 sources.

For purposes of presentation, tube/channel/conduit elements are presented as separate elements in some examples, and in particular are described as being separately assigned to EWS 106 and IWS 126 (e.g., via function groups 204 and 206). However, it should be understood that these elements are optionally shared by being in a fluid interconnection, with control by the EWS 106, IWS 126, or a combination thereof. Control is conferred, shared, and/or transferred, e.g., by the use of control valves 138, 140, 144, 146. In some embodiments, evacuation tube 152 joins to (and optionally comprises) working channel 134, with working channel 134 being joined (e.g., by means of a Y-tube connection) to both the EWS 106 (e.g., via control valve 138) and to the IWS 126 (e.g., via control valve 146). Additionally or alternatively, evacuation tube 152 and working channel 134 together comprise a single channel within the insertion tube, for example as a single tube shared between EWS 106 and IWS 126, or as a plurality of tubes shared between EWS 106 and IWS 126. Some potential advantages of this stem from joint and/or or alternative application of suction to the same channel. For example, in some embodiments, IWS 126 directly provides a high throughput alternative and/or additional mode of operation to the same working channel used for evacuation by EWS 106 (e.g., by application of a higher level of suction). In some embodiments, one of EWS 106 and IWS 126 provides capability for modulation of evacuation pressure, while the other provides a constant or merely on/off source of evacuation pressure. Optionally, the modulation is sensor-driven. For example, upon the sensed occurrence of blockage and/or the beginning of obstruction, one of EWS 106 and IWS 126 operates to clear the block by reversing pressure, while vacuum pressure from the other is optionally switched off, or alternatively left on but modulated by pressure changes driven by the other. Sharing a tube allows the blockage clearance and/or other sensor driven capabilities of one station to assist the evacuation capabilities (perhaps more basic) of the other station. In some embodiments, there are a limited number of conduits available, and it is preferred to concentrate evacuation to, e.g., just one of them, so that another is available as a working channel for a tools. Potentially, one of EWS 106 and IWS 126 is more aggressive in applying suction, and it is preferred to have this aggressive suction active only at selected times—for example, during cleaning under the active guidance of an operator. This potentially increases safety of the device at other times, improves handling, makes control of insufflation level easier, and/or reduces pump noise or other evacuation-related side effects. In some embodiments, the device is configured to switch between using one tube for evacuation and two (that is, switch between using a lesser and greater number of tubes), allowing reconfiguration of evacuation capacity (e.g., in the midst of a procedure) to suit the changing demands of different phases of the procedure.

Additionally or alternatively, in some embodiments, fluid supply tube 154 joins to (and optionally comprises) fluid supply tube 148, with fluid supply tube 148 being joined (e.g., by means of a Y-tube connection) to both the EWS 106 (e.g., via control valve 140) and the IWS 126 (e.g., via control valve 144). Additionally or alternatively, fluid supply tube 154 and fluid supply tube 148 together comprise a single channel within the insertion tube; for example as a single tube shared between EWS 106 and IWS 126, or as a plurality of tubes shared between EWS 106 and IWS 126. As for evacuation, sharing a single tube potentially frees up another tube for other uses in some embodiments. As for evacuation, sharing one or more tubes potentially allows cross-provision of capabilities. For example, IWS 126 may be configured to supply a different fluid or mix of fluids (e.g., an air/liquid mix for producing jets) than EWS 106. In some embodiments, the device is configured to switch between using one tube for fluid supply and two (that is, switch between using a lesser and greater number of tubes), allowing reconfiguration of irrigation capacity (e.g., in the midst of a procedure) to suit the changing demands of different phases of the procedure.

Reference is now made to FIG. 2A-2B, which are a simplified block diagrams of a mode of operation of IECS 100 in accordance with some embodiments of the invention. As shown in the exemplary embodiments depicted in FIG. 2A-2B and disclosed elsewhere herein, IECS 100 comprises at least three function groups:

a) An endoscope operating function group 202 controlled by an operator 250 and optionally by EWS 106 and comprising at least one or more endoscope angulation controls and navigation cables, light wiring and circuitry, power circuitry, image acquisition camera and circuitry and sensors and associated circuitry;

b) An ECS 150 function group 204 controlled by EWS 106 and comprising one or more suction/working channels 134 and one or more irrigation and/or air 178/water 170 supply tubes coupled to air 108 and/or water 110 sources via one or more valves 140. In some embodiments, one or more suction/working channels 134 are functionally coupled to vacuum source 112 via one or more suction control valves 138. In some embodiments, suction/working channels 134 and one or more irrigation and/or air 178/water 170 supply tubes are one or more irrigation and/or air/water supply tubes disposed at least in part through endoscope 101 insertion tube 118. Additionally and optionally, ECS 150 function group 204 comprises sensors and their associated circuitry in communication with EWS 106 processor 114.

c) An ICS 155 function group 206 controlled by IWS 126 and comprising one or more irrigation and/or air/water supply tubes coupled to air 128 and/or water 120 sources via one or more valves 144 and one or more evacuation conduits 152 in fluid communication with vacuum source 122 via one or more vacuum control valves 146. In some embodiments, one or more evacuation conduits 152 and/or one or more air/water supply tubes 154 are disposed at least in part through endoscope 101 insertion tube 118. Additionally and optionally, ICS 155 function group 206 comprises sensors and their associated circuitry in communication with IWS 126 processor 124.

In the exemplary configuration depicted in FIGS. 2A-2B, an operator 250 toggles manually between operation of ECS 150 alone, ICS 155 alone or joint manual activation of ECS 150 and ICS 155. In some embodiments, ICS 155 comprises fluid jet nozzles (not shown) configured to agitate and break up matter in the examined lumen e.g., fecal matter in the colon. The manual mode of operation provides for local imaging and cleaning of a portion of a colon employing ECS 150 when needed and activation of ICS 155 under conditions in which the ability of ECS cleaning operation is insufficient and requires supplementary cleaning and/or agitation and break up of matter in the examined lumen. In some embodiments, one or more directional jet nozzles are located on a camera head and directed by IWS 126.

In some embodiments, ECS function group 204 and/or ICS function group 206 enter endoscope 101 via interface portion 116 and are accommodated within endoscope 101 insertion tube 118 (FIG. 1). In some embodiments, ECS 150 group 204 and optionally endoscope operating group 202 are controlled and supplied from air 108/water 110 and or vacuum 112 sources by EWS 106. In some embodiments, ICS 155 group 206 is independently controlled and supplied from air 128/water 120 and or vacuum 122 sources in IWS 126.

In some embodiments and as shown in FIGS. 2A-2B, IECS 100 comprises one or more mode of operation toggle switches 142. In some embodiments, mode of operation toggle switch 142 is configured to be adjusted manually by an operator 250 or, alternatively and optionally, by an IECS 100 computer (not shown) and set at a desired mode of operation. In some embodiments, mode of operation toggle switch 142 is optionally set to operate ECS 150. EWS 106 is configured to activate and operate at least air 108/water 110 and/or vacuum 112 sources as well as air/water control valve 140 and suction control valve 138 respectively corresponding to the setting of mode of operation toggle switch 142.

In the exemplary configuration shown in FIGS. 2A-2B, air and/or water flow through endoscope supply and/or irrigation tubes 140 disposed in ECS 150 group 204 and vacuum source 112 supplies endoscope working channel 134 with suction. EWS 150 controls one or more suction control valves 138 and one or more air/water supply valves 140.

In some embodiments, mode of operation toggle switch 142 is optionally set to operate ICS 155. IWS 126 is configured to activate and operate at least air 128/water 120 and/or vacuum 122 sources as well as air/water control valve 144 and suction control valve 146 respectively corresponding to the setting mode of operation toggle switch 142.

In the exemplary configuration shown in FIGS. 2A-2B, air and/or water flow through endoscope supply and/or irrigation tubes 154 disposed in ICS 155 group 206 and vacuum source 122 supplies evacuation conduit 152 with suction. CSWS 155 controls one or more suction control valves 146 and one or more air/water supply valves 144.

Distinguishing between FIGS. 2A and 2B, function groups 206 and 204 are shown merged to a single group of tubes. In some embodiments, irrigation tubes 154 and 148 are merged (e.g., at Y-connector 171) and continue as a single tube through insertion tube 118. In some embodiments (additionally or alternatively) evacuation conduit 152 and working channel 134 are merged (e.g., at Y-connector 172) and continue as a single tube through insertion tube 118.

In some embodiments, the merging is four-way; e.g. irrigation tubes 154 and 148 are merged at a four-way connector to connect to both of control valves 140, 144, and/or evacuation conduit 152 and working channel 134 are merged at a four-way connector to connect to both of control valves 138, 146.

Although drawn separately in other embodiments herein for purposes of presentation, it should be understood that in alternative embodiments of any of these, function group 206 and function group 204 share one or more tubes (e.g., by 3-way and/or 4-way connections) for example as just described in relation to FIG. 2B, and/or as described in relation to FIG. 9 and/or FIG. 1, herein.

ICS/ECS Master/Slave Mode of Operation

Reference is now made to FIGS. 3A, 3B and 3C, collectively referred to as FIG. 3, which are simplified block diagrams of a mode of operation of IECS 100 in accordance with some embodiments of the invention. As shown in the exemplary embodiment depicted in FIGS. 3A-3C, in some embodiments, mode of operation toggle switch 142 is optionally set to operate ICS 155 and ECS 150 in a respectively Master/Slave mode of operation.

In the exemplary configuration depicted in FIGS. 3A-3C, ICS 155 is configured to control IWS 155 valves 144/146 as well as EWS 150 valves 138/140 as indicated by an arrow 350. In this configuration ICS 155 is configured to operate independently and automatically activate ECS 150 when needed. For example, in a colonoscopy procedure IECS 100 is introduced into the colon and advanced along the colon up to the cecum. In some embodiments, ICS 155 is activated e.g., to cleanse the colon in preparation for an imaging portion of the procedure. The cleansing process is carried out concurrently with the advancement of IECS 100 in the colon.

In some embodiments, ICS 155 evacuation conduit 152 comprises one or more sensors 302 that communicate operating parameters e.g., lumen pressure and flow of matter in evacuation conduit 152 lumen to IWS 126 processor 124. In some instances, for example, ICS 100 encounters partial or full blockage of evacuation conduit 152 that is reflected by a fall in pressure in the lumen of evacuation conduit 152 sensed by sensor 302 and communicated to IWS 126. IWS 126 is configured to automatically activate ICS 155 based on the received parameters to supplement cleansing operation of ICS 155.

In another example: in some instances during a procedure IECS 100 encounters excessive amounts of matter requiring supplemental suction and evacuation in which case and as depicted in FIGS. 3A-3C by an arrow designated reference numeral 350, IWS 155 additionally and optionally is configured to activate EWS 150 one or more valves 138 and/or 140 as needed.

In the exemplary embodiment depicted in FIG. 3B, ICS is activated and receives information regarding operating parameters of the ICS from one or more ICS sensors. In some embodiments, the data is received in a continuous or intermittent manner. In FIG. 3B the operating parameter comprises a pressure parameter indicating e.g., pressure inside ICS evacuation conduit 152. A fall in pressure (a “Low” indication) may indicate partial or complete blockage of the evacuation conduit 152 bringing ICS 155 IWS 126 to activate ECS 150 to evacuate matter e.g., from a colon.

In the exemplary embodiment depicted in FIG. 3C, ICS is activated and receives information regarding operating parameters of the ICS from one or more ICS sensors. In some embodiments, the data is received in a continuous or intermittent manner. In FIG. 3C the operating parameter comprises a matter volume parameter indicating e.g., high volume of matter inside ICS evacuation conduit 152. Hi volume indication (a “HI” indication) may indicate e.g., too high a volume of matter in a colon for ICS 155 evacuation conduit 152 to evacuate alone bringing ICS 155 IWS 126 to activate ECS 150 to evacuate excessive matter from the colon.

Although drawn separately for purposes of presentation in FIG. 3A, it should be understood that in some embodiments, ICS 155 group 206 and ECS 150 group 204 share one or more tubes, for example as described in relation to FIG. 2B, FIG. 9 and/or FIG. 1, herein.

EWS/IWS “Smart” Master/Slave Mode of Operation

Reference is now made to FIGS. 4A, 4B and 4C collectively referred to as FIG. 4, which are simplified block diagrams of a mode of operation of IECS 100 in accordance with some embodiments of the invention. As shown in the exemplary embodiment depicted in FIGS. 4A-4C, in some embodiments, mode of operation toggle switch 142 is optionally set to operate ECS 150 and ICS 155 in a respectively Master/Slave mode of operation. Alternatively and optionally, mode of operation toggle switch 142 is optionally set to operate ICS 155 and ECS 150 in a respectively Master/Slave mode of operation.

In some embodiments, a lumen of at least one of ECS 150 working channel 134 and ICS 155 evacuation conduit 152 comprises one or more sensors disposed in one or more corresponding

ECS 150 and ICS 155 components being in data communication with corresponding EWS 106 and IWS 126. In some embodiments, the one or more sensors comprise at least one of a pressure sensor, contact sensor and flowmeter. In the exemplary configuration depicted in FIGS. 4A-C, a sensor 402 is disposed in a lumen of working channel 134 providing EWS 106 processor 114 data regarding working channel 134 operating parameters e.g., lumen pressure and flow of matter in working channel 134 lumen. In some embodiments, sensor 402 is configured to alert EWS 106 processor 114 when lumen of working channel 134 is blocked e.g., by a tool. In some embodiments, the operating parameters include parameters originating from function group 202 e.g., image acquisition data as indicated in FIGS. 4A-4C by an arrow 456.

In the configuration depicted in FIGS. 4A-4C, ECS 150 is activated and operating parameters described elsewhere herein are communicated e.g., from sensor 402 and/or valves 138/140 to EWS 106 processor 114 as indicated by arrow 450 and from EWS 106 processor 114 to IWS 126 processor 124 indicated by arrow 454. Additionally and optionally, operating parameters, e.g., rate of flow, fluid level, fluid weight and fluid pressure are communicated from ECS 150 components e.g., from EWS 106 air 108 and/or water 110 sources to EWS 106 processor 114 as indicated by arrow 452 and from EWS 106 processor 114 to IWS 126 processor 124 indicated by arrow 454. Additionally and optionally, operating parameters, e.g., image information, are communicated from ECS 150 function group 202 components e.g., camera (not shown) to EWS 106 processor 114 indicated by arrow 456 and from EWS 106 processor 114 to IWS 126 processor 124 indicated by arrow 454.

In the exemplary embodiment shown in FIGS. 4A-4C, IWS 126 processor 124 is configured to process the operating parameters received from EWS 106 processor 114 as explained elsewhere herein and automatically activate ICS 155 based on the received parameters. For example and in some embodiments, in a colonoscopy procedure, following introduction and advancement of IECS 100 into the colon, a user 250 employs function group 202 to image the colon as IECS 100 is gradually retracted from the cecum and gradually out of the colon. In some instances, ICS 155 is activated e.g., to cleanse the colon in areas in which a field of view is blocked by colon lumen matter e.g., fecal matter.

In some instances the ability of ECS cleaning operation is insufficient and requires supplementary cleaning and/or agitation and break up of matter in the imaged lumen. In some embodiments, IWS 126 receives operating parameters, e.g., image information, communicated from ECS 150 function group 202 components e.g., camera (not shown) via EWS 106 processor 114. IWS 126 is configured to automatically activate ICS 155 based on the received operating parameters e.g., image information to supplement cleansing operation of ECS 150. Once parameters return to acceptable levels e.g., clear received image, indicating that supplemental cleansing is no longer needed, IWS 126 is configured to automatically stop ICS 155 activity based on the received operating parameters.

In another example, in some instances working channel 134 is clogged or blocked by matter suctioned from lumen of a colon. A fall in pressure in a lumen of working channel 134 is sensed by a sensor e.g., sensor 402, and communicated to IWS 126 via EWS 150. IWS 126 is configured to automatically activate ICS 155 based on the received parameters to supplement cleansing operation of ECS 150. Once parameters return to acceptable levels e.g., working channel 134 lumen pressure is normal, indicating that supplemental cleansing is no longer needed, IWS 126 is configured to automatically stop ICS 155 activity based on the received operating parameters.

In the exemplary embodiment depicted in FIG. 4B, ECS 150 is activated and ICS 155 receives information regarding operating parameters of ECS from one or more ECS sensors. In some embodiments, the data is received in a continuous or intermittent manner. In FIG. 4B the operating parameter comprises a pressure parameter indicating e.g., pressure inside ECS working channel 134. A fall in pressure (a “Low” indication) may indicate partial or complete blockage of the working channel 134 bringing ICS 155 IWS 126 to activate ICS 155 to evacuate matter via ICS evacuation conduit 152; e.g., from a colon.

In the exemplary embodiment depicted in FIG. 4C, ECS 150 is activated and ICS 155 receives information regarding operating parameters of ECS 150 from one or more ECS sensors. In some embodiments, the data is received in a continuous or intermittent manner. In FIG. 4C the operating parameter comprises a matter volume parameter indicating, e.g., a high volume of matter inside ECS working channel 134. Hi volume indication (a “HI” indication) may indicate e.g., too high a volume of matter in a colon for ECS 150 working channel 134 to evacuate alone bringing ICS 155 IWS 126 to activate ICS 150 evacuation channel 152 to evacuate excessive matter from the colon.

Although drawn separately for purposes of presentation in FIG. 4A, it should be understood that in some embodiments, ICS 155 group 206 and ECS 150 group 204 share one or more tubes, for example as described in relation to FIG. 2B, FIG. 9 and/or FIG. 1, herein.

In some embodiments, the operating parameters include parameters originating from function group 202; e.g., image acquisition data as indicated in FIGS. 5A-5C by an arrow 456.

In the configuration depicted in FIGS. 5A-5C, ECS 150 is activated and operating parameters described elsewhere herein are communicated e.g., from sensor 402 and/or valves 138/140 to EWS 106 processor 114 as indicated by arrow 550. Additionally and optionally, operating parameters, e.g., rate of flow, fluid level, fluid weight and fluid pressure are communicated from ECS 150 EWS 106 components e.g., air 108 and/or water 110 sources, to EWS 106 processor 114. Additionally and optionally, operating parameters, e.g., image information, are communicated from ECS 150 function group 202 components e.g., camera (not shown) to EWS 106 processor 114 indicated by arrow 456.

In the exemplary embodiment shown in FIGS. 5A-5C, EWS 106 processor 114 is configured to process the received operating parameters and activate ICS 155 based on the received operating parameters. For example and in some embodiments, in a colonoscopy procedure, following introduction and advancement of IECS 100 into the colon, a user 250 employs function group 202 to image the colon as IECS 100 is gradually retracted from the cecum and gradually out of the colon. In some instances, ICS 155 is activated e.g., to cleanse the colon in areas in which a field of view is blocked by colon lumen matter e.g., fecal matter.

In some instances the ability of ECS cleaning operation is insufficient and requires supplementary cleaning and/or agitation and break up of matter in the imaged lumen. In some embodiments, EWS 106 is configured to automatically activate ICS 155 as indicated by arrow 552 based on the received operating parameters to supplement cleansing operation of ECS 150.

In another example, in some instances working channel 134 is clogged or blocked by matter suctioned from lumen of a colon. A fall in pressure in a lumen of working channel 134 is sensed by a sensor e.g., sensor 402, and communicated to EWS 150. As described elsewhere herein, EWS 106 is configured to automatically activate ICS 155 as indicated by arrow 552 based on the received operating parameters to supplement cleansing operation of ECS 150.

In reference to Master/Slave operating modes described herein, at least one of ECS/ICS/EWS/IWS designated as a Master operating system is operative to activate at least one of corresponding ECS/ICS/EWS/IWS designated as a Slave operating system continuously or intermittently and/or inactivate at least one of corresponding ECS/ICS/EWS/IWS designated as a Slave operating system when received operating parameters as described elsewhere herein indicate that operation of a Slave operating system is no longer required.

In the exemplary embodiment depicted in FIG. 5B, ECS 150 is activated and receives information regarding operating parameters of ECS from one or more ECS sensors. In some embodiments, the data is received in a continuous or intermittent manner. In FIG. 5B the operating parameter comprises a pressure parameter indicating e.g., pressure inside ECS working channel 134.

In the exemplary embodiment depicted in FIG. 5C, ECS 150 is activated and receives information regarding operating parameters of ECS 150 from one or more ECS sensors. In some embodiments, the data is received in a continuous or intermittent manner. In FIG. 5C the operating parameter comprises a matter volume parameter indicating, e.g., a high volume of matter inside ECS working channel 134.

Reference is now made to FIG. 6, which is a simplified block diagram of an IECS mode of operation toggle switch in accordance with some embodiments of the invention. In the exemplary embodiment depicted in FIG. 6 toggle switch 142 is configured to select between one or more modes of operation including: (a) Off mode 602 in which IECS 100 is turned off.

Although drawn separately for purposes of presentation in FIG. 5A, it should be understood that in some embodiments, ICS 155 group 206 and ECS 150 group 204 share one or more tubes, for example as described in relation to FIG. 2B, FIG. 9 and/or FIG. 1, herein.

Reference is now made to FIGS. 7A and 7B; which are a simplified flow chart of implementation of IECS 100 in a colonoscopy procedure in accordance with some embodiments of the invention. A colonoscopy procedure commonly requires preparation to cleanse out the content of the colon and to allow proper imaging of the colon wall. However, in some instances, preparation is incomplete, insufficient or has not been done at all. In such circumstances a colonoscopy comprises at least two phases: a cleansing phase that is carried out concurrently with the introduction of the colonoscope into the colon and an imaging phase that follows the cleansing phase and is commonly carried out during the colonoscope withdrawal from the colon.

As explained in greater detail elsewhere herein, IECS 100 comprises an ICS 155 configured to agitate and break down colon lumen fecal matter so to enable effective evacuation of the matter out of the colon.

In some embodiments and as described elsewhere herein, an exemplary and optional method of implementing IECS 100 in a colonoscopy procedure comprises at 702 introducing IECS 100 into a colon and adjusting at 704 IECS mode of operation toggle switch 142 to ICS/ECS Master/Slave mode of operation 606/612 and activating ICS 155 at 706. The method further comprises at 708 guiding IECS 100 through the colon while concurrently cleansing the colon with ICS 155. At 710 optionally activating or inactivating ECS 150 optionally automatically as needed throughout the advancement of IECS 100 to supplement the cleansing operation of ICS 155 and reaching the cecum at 712. This completes the cleansing phase of the colon at which time the imaging phase of the method begins at 714 in adjusting IECS mode of operation toggle switch 142 to ECS/ICS Master/Slave mode of operation 610/614 and at 716 starting image acquisition while gradually retracting IECS 100 in the colon away from the cecum. Optionally, at 718, activating ECS 150 and optionally at 720 activating or inactivating ICS 155 optionally automatically as needed throughout the retraction of IECS 100 along and out of the colon to supplement the cleansing operation of ECS 150 until fully removing IECS 100 from the colon at 722.

In some embodiments, ICS 155 function group 206 and endoscope operating function group 204 are configured to at least partially overlap in the tubes belonging to each, and share control of evacuation and/or fluid supply. In some embodiments, evacuation tube 152 joins to (and optionally comprises or is identical to) working channel 134, with one or both of working channel 134 and evacuation tube 152 being joined (e.g., by means of a Y-tube connection) to both the EWS 106 (e.g., via control valve 138) and to the IWS 126 (e.g., via control valve 146). Additionally or alternatively, in some embodiments, fluid supply tube 154 joins to (and optionally comprises or is identical to) fluid supply tube 148, with one or both of fluid supply tube 148 and fluid supply tube 154 being joined (e.g., by means of a Y-tube connection) to the EWS 106 (e.g., via control valve 140) and to the IWS 126 (e.g., via control valve 144).

In some embodiments, a diameter of insertion tube 118 is between 17 and 22 mm, between 18 and 20 mm, less than 17 mm, more than 22 mm or any diameter in between. In some embodiments, a diameter of insertion tube 118 is equal to 19 mm. In some embodiments, a diameter of insertion tube 118 is less than 19 mm. In some embodiments, one or more evacuation conduits 152 comprises a diameter in the range between 2 and 10 mm, 4 and 8 mm or 5-6 mm, less than 2 mm or more than 10 mm and any diameter in between. In some embodiments, the diameter of evacuation conduits 152 is between 5.4 mm and 6.0 mm. In FIG. 9, the components of insertion tube 118 are depicted distanced from one another for clarity of explanation.
